I would say apples and oranges because those are both teh same they are fruits. Xball and NPPL are both paintballbut completely different.
I have talked about this with my teamates and honestly i enjoy both formats. I dont think i would want to stop playing either one. I know you were looking for a definate answer for me to pick one or the other but i cant. I definately like the format of practice for x-ball. Alot of games. The more the better. I do like NPPL because you can be sneaky!!!
I didnt really like NXL play that much because no one there was playing for anything so they all ran around like chickens with thier heads cut off. Pro Divsion X-ball has more on the line and the games are more controlled.

Well, I can pick one. I like X ball. Because win or lose, when your done with a match you know the better team had more points. Now of course there are those times when your tied with seconds left and some really crazy cheating and run throughs happen, ie Russian game at CUP....lol. But never the less, you had all the opprotunites in 36 minutes to win......it wasn't decided with one 7 minute game where you had a couple one for ones cuz of some Nazi Euro reffs on a field that sucked...ie Russians at San Diego....lol. Damn Russians.....lol.
